    I am getting no intellisense and design time errors when using the Bound method to declare columns.  When I run the site it works fine, but isn't the whole point of using the lambda instead of magic strings so I can get accurate design time errors?

    In the following code, I get design time errors for each of the lambdas in the columns.Bound declarations.  Am I doing something wrong?

        .Columns(columns => {
            columns.Bound(u => u.Email).ClientTemplate("<a>#: Email #</a>");
            columns.Bound(u => u.IDUserRole);
            columns.Bound(u => u.FirstName);
            columns.Bound(u => u.LastName);
            columns.Bound(u => u.IsOnLine);
        .Pageable(paging => paging.Enabled(true).PageSizes(new int[]{5, 10, 20, 50}))
        .Selectable(select => select.Type(GridSelectionType.Row).Mode(GridSelectionMode.Multiple))
        .DataSource(dataSource => dataSource
            .Read(read => read.Action("Users_Read""Users"))

    Hello Kevin,

    The provided code snippet works correctly on my side. Feel free to send a standalone project for inspection after checking whether there is some problem not related to the Grid.
